SPECIFICATION forming part of Letters Patent No. 305,960, dated .September 30, 1884.-.

Application led July 15, 1884. (No model.)

To aZZ'u/tom it may concern.'

Be it known that I, CHARLES M. PIERCE, a citizen of the United States, residing at Bridgeton, in the county of Cumberland and State of New Jersey, haveinvented a new and useful Sawing-Machine, of which the following is a specification, reference being had to l[he accompanying drawings.

This invention has relation to wood-sawing machines, and it has for its object to provide a machine of the class referred to that shall possess superior advantages in point of simplicity, speed, economy, durability, and general efciency; and the invention consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a view in perspective of a sawing-machine embodying my improvements. Fig. 2 is a side elevation. Fig. 3 is a vertical longitudinal sectional View.

Referring by letter -to the accompanying drawings, A designates the frame of the machine, which is provided at one end with the driving-shaft A', provided with the crankhandle A2 and the large sprocket-wheel B.

In suitable bearings at the other end of the frame A is provided a crank-shaft, C, having a small sprocket-wheel, C, at one end and a balance-wheel, D, at the other end. A sprocket-chain, E, connects the sprocket-wheels B and O. y

E designates the pitman which connects the saw-frame G to the crank-shaft C. The saw-frame G is provided with a saw-blade, II, and said frame G works between parallel guides I I', secured near one end of the frame to the under face of a cross-bar, J, connected to the top side rails of the frame A, and at their other ends to a slotted upright, K, secured to the inner faces of the top cross-rail, L, and the lower cross-rail, M. Aguide-rod, N, is connected to the front end of the sawframe G, and extends forward through the slot in the upright K, and is provided on its end with a weight, O. A guide-rod, I), is connected to the rear lower corner of the sawframe G, and works through an iron guideblock, Q, on a cross-bar, Q, at the rear end of the frame A. -The saw-horse R is made of l two V-shaped pieces, connected at their bottoms by a piece, S, and arms of the outer V are connected at their tops by two parallel pieces, T T, to the side rail, U, leaving this V open. The connecting-pieces S and T T are let into the face of the longitudinal rail U and the side rail, V, and are secured by bolts. The longitudinal guide-rail I is bolted to the tops of the arms of the inner V of the sawhorse, andaspace is left between the side rail, 6o V, and the guide-rail I, in which the clamp Wfor holding the stick or sticks of wood to be sawed is worked up and down.

The clamp W consists of a bar, VV, running longitudinally of the frame A, and pivoted near its rear end to the inner face of the Side rail V, and connected at its rear end to the upper end of a spiral spring, X, the lower end of which is connected to the inner face of the longitudinal rail U. 7o

Directly over the piece S of the saw-horse the'bar W" is provided on its under face with inverted-V-shapedjaws Y, which are intended to hold the stick of wood or anuniber of small sticks of wood in place in the saw-horse, when the dog Z on the bar XV near its front end is in engagement with the proper notch of the rack Z', secured to the upright Z`l at the front end of the frame.

A full-sized machine weighs about one hun- 8o dred pounds. I have cut one-eighth of a cord of wood in three cuts in twenty minutes on the first trial with this machine, and can now do more rapid work.

Having thus fully described my invention, 8 5 what I claim as new, and desire to secure by Letters Patent ofthe United States, isn

1. The combination, with the frame having the V-shaped saw-horse, the pivoted springactuated clamp with inverted-V-jaws and dog 9o and rack, the upper parallel saw-guides, the slotted upright at one end and the iron guideblock at the other end, of the saw-frame having the weighted guide-rod working in the slotted upright, the rear guide-rod working in the iron guide-block, the driving-shaft having crank and large sprocket-wheel, the sprocketchain, the crank-shaft having small sprocketwheel and balance-wheel, and the pitman connecting the crank-shaft and saw-frame pro- ICO vided wit-h the saw-b1ade, substantially as the inVerted-V-shaped jaws, und the dog` Z specified. and the mok Z7 secured to the upright Z2 2. The combination, with the frame of a substantially as specified. sawing-machine, of the saw-horse composed In testimony thzttolaim the foregoing` as my 5 of the V-shaped ends connected at their lower own Ihave hereto affixed my signature in pres- 15 ends by the cross-piece S,1et into the longience of two witnesses.
